Sioux Chief 821 Series ABS Shower Drain Base & Collar

The Sioux Chief 821 Series is a family of 2" ABS shower drain base and collar assemblies built for rough-in installation beneath a shower pan or base, available as model 821-HA2 or model 821-MHA2. Manufactured from ABS plastic, each base-and-collar unit in this series provides the sub-floor connection point that mates to the drain body above and the waste line below, giving plumbers and contractors a solid foundation for the finished shower drain assembly. Made in the United States, the series is supplied 25 EA to a case for distributors and contractors stocking rough-in drain components for new construction and remodel work.

Key Features

  • Trade Size: 2" outlet sizing for standard shower drain rough-in connections across both 821-HA2 and 821-MHA2 models.
  • Durable Construction: Molded ABS plastic base and collar resists the corrosion and cracking that can affect behind-the-wall drain components over time.
  • Base & Collar Design: Combined base and collar configuration simplifies rough-in installation by pairing the sub-floor mounting base with the matching collar in a single part.
  • Model Options: Choose between the 821-HA2 and 821-MHA2 configurations to match the specific rough-in requirement for a given job.
  • Rough-In Ready: Designed to be set and connected to the waste line before the shower pan or base is installed, keeping the finished drain assembly square and level.
  • Contractor Packaging: Packed 25 EA per case for efficient stocking and job-site distribution.
  • Domestic Manufacturing: Produced in the United States as part of Sioux Chief's rough-in plumbing product line.

Sioux Chief 821-HA2 – Frequently Asked Questions

1) Will the Sioux Chief 821-HA2 shower drain base connect to 2 inch ABS waste pipe?
Yes. The 821-HA2 is a 2 inch ABS base and collar, so it mates to standard 2 inch ABS waste line below and the drain body above. Because the part itself is ABS, it solvent welds with ABS cement to ABS pipe. If your waste line is PVC, you are joining dissimilar plastics and that is a transition joint, not a straight solvent weld.
2) What does a shower drain base and collar actually do, and do I still need a drain body?
The base and collar is the rough-in half of the assembly. It sets below the shower pan, ties into the waste line, and carries the collar that the drain body above threads or clamps to. It is not a finished drain on its own, so you still need the drain body and strainer to complete the job.
3) Can I install the Sioux Chief 821-HA2 after the shower pan is already set?
No. The 821-HA2 base and collar is meant to be set and connected to the waste line before the shower pan or base goes in, which is what keeps the finished drain assembly square and level. On a pan replacement you pull the pan first, then work the rough-in.
4) What is the difference between the Sioux Chief 821-HA2 and the 821-MHA2?
Both are 2 inch ABS shower drain base and collar assemblies in the same 821 Series; they are two configuration options you pick to match the rough-in requirement on the job. Order by the exact model number, 821-HA2 or 821-MHA2, so the collar matches the drain body you are pairing it with.
5) How is the 821-HA2 packaged, and can I buy a single one?
Sioux Chief supplies the 821 Series 25 each per case, which is how it is stocked for contractors and distributors running volume rough-in work. If you only need one for a single pan swap, order by the piece rather than the case.
6) Will an ABS shower drain base hold up behind the wall long term?
Molded ABS is used here specifically because it does not corrode the way metal rough-in drain parts can, and it resists cracking in a concealed sub-floor location. For property managers standardizing across many units, ABS also keeps the rough-in consistent unit to unit.
